Specification of Letters Patent.

Patented Jan. 4, 1916.

Application filed November 29, 191-2. Serial No. 733,953.

alarm devices, adapted more, particularly for use on automobiles. For example, my invention is useful in connection with whistles, or so-cal-led automobile horns, which are operated by the engine exhaust. In devices of this kind the whistle .or other alarm must be out off from the exhaust when it is not in use. Furthermore, and with a device of this kind, it is often neces sary to clean the openings or passages thereof, owing to the tendency toward the formation of accumulations therein. For example, the said passages may become filled with dust or dirt, or with the soot or other products of combustion from the engine, and in such case the whistle or other alarm will not operate.

Generally stated, the object of my invention is to provide an improved construction and arrangement for a whistle or alarm of this kind, in which the fluid pressureis supplied by the exhaust from an internal combustion engine, and in which means are provided for automatically cleaning the openings or passages thereof, as well as controlling the exhaust to produce the desired result;

Special objects are .to provide a whistle or alarm of this kind in which the fluid pressure passagesare cleaned by projections or lugs on a valve or other member which controls the escape of the exhaust into the atmosphere; to provide, in a structure of this kind, a sliding sleeve for covering the openings through which the exhaust passes when the alarm is sounded; to provide an internal valve for controlling the exhaust, whereby the fluid pressure is directed either directly into the atmosphere, or indirectly through the whistle or other alarm device; and to provide certain details and features of construction and combinations tending to increase the general efiic iency and service ability of a whistle'or other alarm device of this particular character.

To the foregoing and other useful ends, :my invention consists in matters hereinafter set forth and claimed;

In the accompanying drawings Figure 1 is a perspective of an automobile chime whistle embodying the principles'of my invention. Fig. 2 is a longitudinal section of said chime whistle. 3 is a section on line '33 in Fig. "2. Fig. 4 is a perspective of the interior valve which is provided with lugs or projections for entering the fluid pressure passages to keep the latter clean. Fig. 5 is a perspective of a portion of the sleeve which slides upon the whistle tubes, and which covers the whistle open' ings when the same are not in useQshowing a modification of my invention.

As thus illustrated, it will be seen that'my invention comprises a rectangular hollow body A having .the square or rectangular whistle tubes 5 suitably mounted on one side thereof, and the said tubes being provided with whistle openings at having edges a against which the fluid pressure impinges to produce the sound. For this purpose the side wall of the body A is provided with slots a which direct the fluid pressure against the said edges a in the manner of an Ordinary whistle. The other side of the body A is provided with a removable plate attend the ends of said body are provided with inlet and outlet pipes B and C, whereby the exhaust from the engine passes entirely through the said body A. when the whistle is not in use. .To .control the exhaust, an internal valve D is provided Within the body.A,'being pivoted at d whereby said Valve is adapted to either open or close the outlet (1, being operated by a crank arm 6Z1, secured to the pivot or axis thereof. In order to keep the passages of clean and clear from dirt or other accumulations, the valve D is provided with lugs d said valve open, whereby the passages a are normally closed by the lugs 61 on the said valve. lVhen it is desired to close the valve D to blow the whistle, as shown in Fig. 2, the string or ccrd E is pulled. When the said cord is released, the spring (Z then restores the valve to normal position.

In order to keep dust and dirt from entering the whistle openings a, a sleeve F is arranged to slide upon the whistle tubes, said sleeve being connected by a rod f with the arm' d to which the said cord is attached. In this way the spring d serves also to keep the sleeve F normally over the whistle openings a, whereby the said openings are protected against clogging while the Whistle is not in use. WVhen the string E is pulled, as previously described, the sleeve F is moved away from the body A, thus uncovering the openings a, and as the valve I) is closed at this time,'the exhaust is forced to escape through-the passages a with the result that the whistle is operated.

If desired, the sleeve F can be provided with lugs 7, as shown in Fig. 5, for entering the passages a for the purpose described. In other words, the said passages can be kept clean by lugs or projections on the sleeve F, in the manner shown in Fig. 5, instead of by lugs or projections on the sleeve D, in the manner previously explained. In any event, though, it will be seen that means are provided for entering the fluid pressure passages to keep the same clean, and that said means are preferably located upon an element which serves like a valve for controlling the exhaust.

From the foregoing, it will be seen that I provide a whistle or other alarm device which is operated by the exhaust from an internal combustion engine, and which is provided with means for keeping the fluid pressure passages clean and in condition to produce a full and clear sound when the 45' said whistle or device is operated. Prior to my invention, as previously explained, whistles or other devices operated by the exhaust from an internal combustion engine vwere liable to clog and become inoperative.

With my improved construction, however, this is not possible, or at least the possibility thereof is greatly reduced, inasmuch. as means are provided for keeping the passages clear and clean. a

I do not limit myself to the exact construction shown and described.
